Question

fit a second degree parabola to the following data : X: 1 2 3 4 5 Y: 1090 1220 1390 1625 1915​

Answer 1

Answer:

Second Order parabola equation is `y = a + bx + cx^2

where,

Sum y = an + b Sum x + c Sum x^2`

Sum xy = a Sum x + b Sum x^2 + c Sum x^3`

Sum x^2y = a Sum x^2 + b Sum x^3 + c Sum x^4`

And a, b, c are constants.

xyx' = x - Mean xx^2x^3x^4x' * yx'^2 *...
